PrettyPrompt Alternative: GPT Master for ChatGPT

Quick Answer

PrettyPrompt describes itself as “A browser extension to help refine and optimize prompts”. GPT Master has a Prompt Optimizer too, with an “Optimize Prompt” button in the ChatGPT composer: compare the rewrite with your original and choose which to send. When a prompt gets the answer you wanted, click “Save to Prompt Library” on it, and next time type // to insert it. After each reply, GPT Master can suggest the next question. You can also sort your chats into folders. GPT Master fits when most of your AI work happens in ChatGPT and you want one extension to improve prompts and keep the ones that work.

Prompt Optimizer in the composer

If you use a prompt improver today, the steps will feel familiar.

Write your draft in the ChatGPT composer and click “Optimize Prompt”, or press Ctrl+Shift+E (Cmd+Shift+E on Mac). The “Optimize prompt” dialog shows the “Optimized” version under a collapsed “Original” row you can open, so you can read what changed. Click “Use this version” to put the rewrite in the composer, “Keep original” to keep your draft, or “Re-optimize” for another pass.

Save the prompts you reuse

An improved prompt helps once. Next time it is buried in an old chat or a notes app.

GPT Master’s Prompt Library keeps your own prompts. Create one with “New prompt”. When a rewrite gets the answer you wanted, click “Save to Prompt Library” on the prompt you sent. Next time, type // in the composer, search your prompts and insert one. Add a blank such as {{topic}} and GPT Master shows a “Fill in this prompt” form before inserting.

The Prompt Packs tab adds ready-made sets, such as Fix My Writing and Explain It to Me. Once added, pack prompts work like your own, and you can edit them.

Folders for your chats

After a few weeks, the ChatGPT sidebar is a long list of similar chat titles.

GPT Master adds folders and subfolders to the sidebar. Give each folder a color and drag chats in. Changes show up in your other open ChatGPT tabs. To clear out old chats, tick several and archive or delete them in one step. Deleting is permanent.

Help after the first prompt

A clearer first prompt helps. Most chats still need several more questions after it.

After a reply, GPT Master can show question chips under a “Follow-ups” label. Click one to ask it. When one line in a reply needs a question of its own, highlight it, click “Ask in Side Chat” and type your question. The answer appears in the right panel, and nothing is added to your main chat.

When a chat gets long, the Minimap in the right panel lists your prompts as an outline. Click a row to jump to that message.

Who GPT Master fits

GPT Master fits people who do most of their AI work in ChatGPT and want one extension from the first prompt onward: improve a draft, save the prompt that worked, reuse it with //, and sort the chats into folders.
